+        To finish the installation, you need to create a DNS resolver file
+        in /etc/resolver/YOUR_DOMAIN. Creating the /etc/resolver directory
+        and the config file requires superuser privileges. You can set things
+        up with an one-liner
+
+            sudo candy setup
+
+        Alternatively, you can execute the following bash script
+
+            sudo mkdir -p /etc/resolver && \\
+              sudo chown -R $(whoami):$(id -g -n) /etc/resolver && \\
+              cp #{etc/"resolver/candy-test"} /etc/resolver/candy-test
+
+        To have launchd start Candy now and restart at login
+
+            brew services start candy
+
+        Or, if you don't want/need a background service you can just run
+
+            candy run
+
+        A sample Candy config file is in #{etc/"candyconfig"}. You can
+        copy it to your home to override Candy's default setting
+
+            cp #{etc/"candyconfig"} ~/.candyconfig
